While none of the "not-Romney"s have great electability, the fact that one or another of them keeps coming up even or ahead of him, despite his tremendous organizational and money advantages, does inform some about his fairly poor electability as well. And the process is losing him the middle as it goes on, even while he fails to convince the right he is their man. Will various flavors of "not-Romney" keep him from clinching it before the convention? Santorum surge two does not seem to be fading so fast. And if it reaches that point, how do you see that playing out? (Other than leading to a Reaganesque Obama "mandate" for a second term?)

Does Romney end up naming Paul or Gingerich as VP to get he final votes? Do the not-Romneys somehow band together behind one of them? And if none of the above then who? No, not Palin.
